Added map loading
Added a note to explain loadMap and defaultMap
Updated load function

There was an incorrect number in the load function (a 2 where there should have been a 3)
Pushed a simple java gui to help making new maps

This works with the load_map version of the main program.

Note that in the c program only bullets and walls can currently be loaded.

All objects created by this gui have a direction. This is ignored by the c program unless it is a bullet.
There was a number wrong!

I got confused between player (2) and bullet (3)
